In MorphOS JPEG datatype is already Altivec accelerated so unfortunately there is very little to gain.

AltiVec acceleration isn't just a matter of flicking a compiler switch though - the AltiVec optimisations in WarpJPEG are certainly not the same as in the MorphOS jpeg.datatype. I've no idea how good the AltiVec code is in the MorphOS datatype - it may be better/faster than WarpJPEG, or vice versa (I don't have the hardware to benchmark them).


True. Just out of interest, did you optimize it yourself or is it based on turbo-jpeg? Or both?
